Gartner Inc., a leading global information technology research and advisory company, recently published their latest report. The key takeaways were that by 2020 the enterprise blockchain market will reach $3 billion in annual revenues with over 100% growth on an annual basis.
The “verb get” is a command that allows you to retrieve information from the remote server. This command can be used in conjunction with other commands.
Get-WmiObject may be used to find out almost anything about a Windows PC and its components.
Get-WmiObject can not only read but also conduct actions on local and distant computers using WMI techniques. This is one of a few PowerShell cmdlets that can interact with the WMI repository to make managing a large number of computers much simpler.
Using Get-WmiObject to Find Classes
This cmdlet may query information from a local machine at its most basic level. All you’ll need is the namespace (most likely rootcimv2, which is the default) and the WMI class that has the information you’re searching for.
There are hundreds of courses to choose from, and you probably haven’t decided which one to utilize yet. We may query all of the accessible classes in a namespace using Get-WmiObject. You may view all of the classes in the rootcimv2 namespace by using Get-WmiObject -List. If you need to inspect classes in a different namespace, you may use the Namespace option in addition.
PS> Get-WmiObject -List NameSpace: ROOTcimv2 Name Methods Properties CIM_Indication {} {CorrelatedIndications, IndicationFilterName, IndicationIde… CIM_ClassIndication {} {ClassDefinition, CorrelatedIndications, IndicationFilterNa……..
WMI Property Collection
After you’ve obtained the class, you should explore and discover what properties it has. Perhaps I’d want to check what operating system is installed on a machine. I could be working on a report and want to check what’s going on on a distant workstation. Instead of specifying one or more local computers, the ComputerName argument of Get-WmiObject allows you to specify one or more distant computers.
DC is the name of my distant computer, which is a domain controller. I’ll have a look at the attributes of the Win32 OperatingSystem class.
PS> Get-WmiObject -ComputerName DC -Class Win32_OperatingSystem SystemDirectory : C:Windowssystem32 Organization : BuildNumber : 9600 RegisteredUser : Windows User SerialNumber : 00252-00108-14656-AA864 Version : 6.3.9600
That’s valuable information, however the operating system name is missing. You do not see all of the properties, as you do with many other PowerShell outputs. We’ll need to utilize Select-Object to get all of the properties back.
Select-Object -Property * | Get-WmiObject -ComputerName DC -Class Win32 OperatingSystem
I can now see a property named Caption, which tells me what Windows version I’m running.
PS> (Select-Object -Property * | Get-WmiObject -ComputerName DC -Class Win32 OperatingSystem).Caption Microsoft Windows Server 2012 R2 Standard
WMI Property Lookup
What if you’re searching for a property that matches a certain value rather than a specific property? We may query all instances of the CIM DataFile class, for example, but that would return every file on the system! Instead, we may use the Filter or Query parameters to filter instances by value. Let’s have a look at both.
For example, suppose I only want to locate instances of CIM DataFile that represent compressed files. Because the Compressed property is a boolean value on each instance, I can use the Filter argument to transmit the filter straight to the WMI provider, which will only return instances with the Compressed property set to True.
Get-WmiObject -Class CIM DataFile -Filter “Compressed =’True’” Get-WmiObject -Class CIM DataFile -Fil
If you know WQL, you may create your own WQL query to choose the class and set the “filter” on your own.
-Query Get-WmiObject “SELECT * FROM CIM DataFile AND Compressed = ‘True’”
WMI Methods Invocation
Get-WmiObject not only can read information from WMI, but it can also facilitate WMI Methods Invocation. One common WMI method that’s invoked is the Create method on the Win32_Process class. There are a few different ways to invoke WMI methods such as using Invoke-WmiMethod, but this can be done with Get-WmiObject as well. We just need to capture a WMI instance and then call the method on that object.
This is an example of launching notepad.exe on a remote machine remotely. As an added benefit, we’re doing so using an alternative credential!
get-credential $cred Get-WmiObject -Query “SELECT * FROM Meta Class WHERE __Class =’Win32 Process’” $process = Get-WmiObject -Query “SELECT * FROM Meta Class WHERE -credential -namespace “rootcimv2” -computername “FOO” $process $cred Produce ( “notepad.exe” )
Last but not least, Get-CimInstance is the successor to this cmdlet. Although utilizing PowerShell Remoting as the default remote connection protocol has various benefits, Get-CimInstance is sometimes more convenient.
Get-WmiObject communicates with distant computers via DCOM, which is frequently accessible. If you wish to utilize Get-CimInstance through WSMAN, you’ll need to activate PowerShell Remoting on remote endpoints otherwise.
